var express = require('express');
var routes = require('./routes');
var login = require('./routes/login');
var register = require('./routes/register');
var http = require('http');
var path = require('path');
var MongoClient = require('mongodb');

var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;

var app = express();




// all environments
app.set('port', process.env.PORT || 3001);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());

app.use(express.static(path.join(__dirname, 'public')));

app.use(express.cookieParser());
app.use(express.session({secret: '1234567890QWERTY'}));

app.use(passport.initialize());
app.use(passport.session());

app.use(app.router);

var dbc;
MongoClient.connect('mongodb://127.0.0.1:27017/mydb', function(err, db) {
    dbc = db;
});



passport.use(new LocalStrategy(
function(username, password, done) {
    var User = dbc.collection('users');
  User.findOne({ name: /^Harry Torry$/i }, function(err, user) {

       console.log(JSON.stringify(user));
      if(!err) done(null, JSON.stringify(user) );
      else done(err, null)  
  });
}
));

// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}

app.get('/', routes.index);



// User stuff
app.get('/login', login.get);
app.post('/login',
passport.authenticate('local', { successRedirect: '/',
                                 failureRedirect: '/login'
                             })
);
app.get('/register', register.get);
app.post('/register', register.post);



http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});

所以这是我的代码。出于某种原因，每当我尝试登录时，它都会说它无法序列化数据，即使我可以 console.log(json.stringify()) 它？

关于问题是什么的任何想法？这是堆栈跟踪。（为了安全起见，我用“mydb”更改了项目名称的所有副本）。

我认为您缺少建立登录会话所需的 passport.serializeUser 功能。从护照文件：

passport.serializeUser(function(user, done) {
  done(null, user.id);
});

passport.deserializeUser(function(id, done) {
  User.findById(id, function(err, user) {
    done(err, user);
  });
});

尝试在 passport.use(new LocalStrategy(...

还要检查这个相关问题：Node.js user authentication using passport
